Église Saint-Martin d'Hix, Romanesque church in Hix, Bourg-Madame, France

Église Saint-Martin d'Hix is a Romanesque church with a single nave and a semicircular apse topped by a dark grey conical roof. The apse is built of large, light tan stone blocks and has a row of carved corbels below the roofline, including one shaped as a rosette and another as a face. Its windows are framed by small columns with carved capitals, and the square tower on the left is built of rubble stone.

Saint-Martin d'Hix is first documented in the 10th-century act of consecration of the Seu d'Urgell cathedral under the name Hysi. In 1063 a pact was signed on its altar between Count Armengol III of Urgell and Count Ramon Guifré of Cerdanya, whose palace stood at Hix. The present Romanesque apse and part of the nave date from the 12th century, and the church was classified as a monument historique on 19 November 1910.

The name Hix derives from the Latin Hysi, recorded in the 10th-century consecration act of the Seu d'Urgell cathedral. The church keeps a 13th-century wooden Christ and a 12th-century polychrome Virgin and Child; the Museu Nacional d'Art de Catalunya in Barcelona holds its 12th-century pine altar frontal, painted with a Christ in Majesty and scenes from the life of Saint Martin.

The church stands in the hamlet of Hix, surrounded by its cemetery, with the western bay of the south wall left free of the graveyard. The square bell tower, built later in rubble stone, is the landmark to aim for when approaching from Bourg-Madame. The door in the south wall keeps its medieval ironwork and Catalan hinges.

In the early 1840s a visitor noted that the church kept a cope embroidered in gold and silk with a German imperial eagle; nobody in Hix could explain how it got there, and one guess was booty taken from a Spanish town in wartime. The cope is not mentioned in the 1910 classification or in the inventories of the wooden statues.
